Description
Technical field
The present invention relates to casting field, particularly the foundry facing technical field.
Background technology
Along with the fast development of China's economic construction in recent years, the output of foundry goods, quality and export volume thereof increase year by year, and be also increasingly high to the requirement of the consumption of cast paint and quality thereof.Compare with water based paint; Because alcohol-base paint only need be lighted drying or volatilization air dry; Have that rate of drying is fast, production efficiency is high, energy savings and shorten advantage such as production cycle; So obtained using widely in China, the annual consumption of China's cast paint can reach 20～250,000 tons, and alcohol-base paint accounts for 60～70% of the total consumption of coating.
General coating is made up of compositions such as refractory aggregate, binding agent, suspending agent, auxiliary agent and solvents; Wherein suspending agent is a most important parts in each component of mold wash; Good suspendability can not only guarantee the homogeneity of each component of coating effectively; Give full play to the function of coating, improve the surface quality of foundry goods; But also help applying, store and transport.So, the research of coating deflocculant has been caused people's great attention, particularly Suspension Agent of Alcohol Based Coatings day by day.
In the past, China is with the suspending agent of sodium bentonite as alcohol-base paint, because its swellability in alcoholic solution is bad, suspension effect is poor, need not at present.The organobentonite that adopted quaternary amine to handle afterwards.It is a kind of suspending agent of alcohol-base paint preferably, and still, organobentonite must adopt xylenes to cause and could use, and xylenes belongs to a kind of chemicals of severe toxicity, has a strong impact on the health of human body, can not satisfy the requirement of green Foundry Production of 21 century; Simultaneously, the organobentonite price is higher relatively, has increased the manufacturing cost of coating products greatly, and is beyond affordability for the foundry enterprise of small profits.After the eighties in 20th century, China has developed a kind of alcohol-base paint again and has used novel suspending agent, and it is to carry out cation exchange and get (CN85105821) with lithium salts and calcium-base bentonite, and this material has good suspension property and serviceability in alcoholic solution.But, behind the lithium bentonite water absorption and swelling, less stable in alcoholic solution; Owing to lithium soil micelle is prone to dehydration in alcoholic solution, deposition makes alcohol-base paint lose suspension effect; Cause refractory aggregate sinking caking in the coating, especially in process is jolted in transportation, often form in " silent as the grave shallow lake "; Worsen the coating serviceability of coating, also reduced the refractoriness and the anti-stick grittiness ability of dope layer.
Application number is that 200910012344.3 one Chinese patent application discloses a kind of attapulgite suspending agent for casting alcohol-based coating, it is characterized in that at Magnesiumaluminumsilicate content being that coating inorganic nanoparticles constitutes on 80～85% recessed grogs with mass percent; Inorganic nano-particle is nanometer Al
2O
3, nanometer SiO
2Or nano-TiO
2, its particle diameter is 10～20nm, specific area is 200～300m
2/ g.Yet, facts have proved this suspending agent owing to adopt the protruding Attapulgite preparation of single component, performance still is not very good, and owing to added nanometer particle, cost is higher.
Summary of the invention
To the deficiency of prior art, one of the object of the invention is to provide a kind of preparation method of casting alcohol-based coating suspending agent.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is following:
A kind of preparation method of casting alcohol-based coating suspending agent, this method comprises the steps:
1) Suspension Agent of Alcohol Based Coatings is made up of the following raw materials according in weight portion: protruding Attapulgite 20-30 part, calcium agent bentonite 30-40 part, sodium carbonate 10-15 part; Polyethylene glycol 1-2 part, sodium metasilicate 5-8 part, zinc oxide 1-2 part; Zirconia 1-2 part is by the said ratio weigh batching;
2) load weighted each batching of step 1) was put into the batch mixer mixing 60-90 minute; Then the compound that mixes is put into agitated reactor, add the phosphate aqueous solution of 50-60%, be warming up to 40-50 ℃ then, reacted 30-40 minute, centrifugal dehydration then, oven dry;
3) with step 2) the oven dry thing that obtains puts into grinding machine and mills, and standard screen is crossed in the back of milling, and the thing of getting between the particle size range 100-320 order of milling is Suspension Agent of Alcohol Based Coatings.
Preparation method's of the present invention beneficial effect is:
1) select for use various ingredients to fit in suspending agent; The advantage that fully utilizes various suspending agents makes that the suspendability of suspending agent is excellent; Can in alcoholic solution, demonstrate good dispersibility and suspension stability; Significantly improve the anti-ability that hardens, adopt the zirconium English powder or 24 hours the suspension of silica flour alcohol-base paint of this suspending agent preparation can reach 97-100%.
